掺杂Fe^(2+),Bi^(3+),Cu^(2+)的PZT陶瓷低温烧结

Reseture of adulterating Fe^(2+) ,Bi^(3+) ,Cu^(2+) on PZT ceramics under low -temperature sintering

在利用水热法合成的粉体低温烧结PZT[Pb(Zr0 .5 3TiO0 .47)O3]陶瓷中 ,掺杂了Fe2 + ,Bi3+ ,Cu2 + 等无机化合物 ,使PZT陶瓷在 85 0℃温度下即可烧成 ,密度可达理论值 98%。压电性能测定表明 ,其Kp值变化不大 ,而Qm值有较大提高。

PZT(Pb(Zr 0.53 TiO 0.47 )O 3) Utilizing hydrothermallysynthesized powder and inorganic components, Fe 2+ ,Bi 3+ ,Cu 2+ is adulteratecl PZT ceramicwe have sintered PZT under 850?℃. Its density achieves 98 percentage of thetheoretical value. Its piezoelectricity performance indicates: slightly decreasethe Kp value of PZT ceramics. Whereas can greatly increase the Qm value.
